Daily chess puzzle: Check Mate #421

September 1, 2017

Another puzzle from Dragoslav Andric’s 1981 book “Matni Udar”.

Black to play and mate White (with a twist: try to find the twist)

Schneider v Graz, Zalaegerszeg 1976

Solution

An unusual position for there to be a win: likely a typical Sicilian opposite side castle race. But knowing it is a problem, the only move has to be 1…Nc3+! forcing 2 bc[] when 2…Nd5 can be seen to be dominant.
